To all Kess3 ECU Programmer users,
Alientech officially released an important update on Kess3 software subscriptions.
Starting on March 27, 2026, KESS3 subscriptions will switch to a new 12-month model, with only three types available.
1.Renewal Costs
Master Version
l Early Renewal: €990
l Normal Renewal: €1,190
l Reactivation (inactive over 12 months): €1,390
Slave Version
l Early Renewal: €490
l Normal Renewal: €590
l Reactivation (inactive over 12 months): €690
Note: All renewal cases now fall under one of these three categories.
2.How It Works
l Early Renewal
Condition: Your subscription is still active—renew before it expires.
How it works: Your new 12-month term starts right after your current term ends.
Advantage: You keep every day of usage and lock in the lowest price.
l Normal Renewal
Condition: Your subscription has expired, but it’s been less than 12 months.
How it works: Your new 12-month term starts on the day you renew.
Advantage: The system automatically covers any gap—no extra charge.
l Reactivation
Condition: Your subscription has been expired for over 12 months.
How it works: Your new 12-month term begins on the reactivation date.
Note: This option represents the highest cost. To avoid this, maintaining a continuous subscription is strongly recommended for your Kess V3.
